I am friends with this girl and we were joking around afterschool and she stole my phone. I tried to take it back but I failed then she licked my arm & bit it softly. She did the same thing everytime I tried to get my phone back but I eventually got it back after threatening to poke her in the eye with my pencil. I've known her for 2 yrs and we're both 18, I`m bi, she`s straight. She`s an odd girl, yes, but doesn't usually do this kind of stuff. So what I`m asking is, is this normal?
